Systemic failure of native in-place operators (add_, scatter_add_, etc.) in static_pir leading to silent value mismatch

### bug描述 Describe the Bug Under the new static_pir infrastructure (paddle.jit.to_static(..., full_graph=True)), multiple native in-place operators (methods ending with an underscore) do not mutate the tensor's state as expected. The compiler appears to drop the Yield/Update state during the SSA graph lowering. Consequently, the static graph silently returns the stale, unmutated tensor. This correctness bug bypasses legality checks and silently corrupts downstream computations, affecting both simple element-wise operations and complex indexed memory operations. ```python import os import paddle paddle.set_device("cpu") def kernel_inplaces(x_simple, x_complex, idx, src): # 1. Simple element-wise in-place x_simple.add_(paddle.to_tensor([10.0, 10.0], dtype="float32")) # 2. Complex indexed memory in-place x_complex.scatter_add_(1, idx, src) return x_simple, x_complex # Initialize data x_simple_init = paddle.to_tensor([1.0, 2.0], dtype="float32") x_complex_init = paddle.zeros([2, 4], dtype="float32") idx = paddle.to_tensor([[1, 3], [2, 0]], dtype="int64") src = paddle.to_tensor([[0.5, 1.25], [-3.0, 4.0]], dtype="float32") # Eager Execution e_simp, e_comp = kernel_inplaces(x_simple_init.clone(), x_complex_init.clone(), idx, src) # Static PIR Execution static_fn = paddle.jit.to_static(kernel_inplaces, full_graph=True) s_simp, s_comp = static_fn(x_simple_init.clone(), x_complex_init.clone(), idx, src) print("=== In-place Operators Silent Failure ===") print(f"[add_] Eager: {e_simp.numpy().tolist()} | Static: {s_simp.numpy().tolist()}") print(f"[scatter_add_] Eager Sum: {paddle.sum(e_comp).item()} | Static Sum: {paddle.sum(s_comp).item()}") ``` Output: ``` === In-place Operators Silent Failure === [add_] Eager: [11.0, 12.0] | Static: [1.0, 2.0] [scatter_add_] Eager Sum: 2.75 | Static Sum: 0.0 AssertionError: Value mismatch: In-place add_ failed! ``` ### 其他补充信息 Additional Supplementary Information _No response_
